My script creates a select using the followig code:

<td colspan="3" rowspan="3" valign="top"><font face="Courier" size="4">
<select name="selChoices" size="10" id="selChoices">
</select>
</font></td>



How do I get the select hide/show at will?

I tried

document.forms["entry"].selChoices.style.visibility = "hidden"

but that does not work.
What is the property for controlling visible/hidden?

Hi!

The property is "hidden".

Are you sure, your <select> is inside a form and the form's name attribute is "entry"???

This is the relevant code with parts cut out. The error I get is visibility property not found.
Help

Hi!

Apart from other things (examples: in the body - face="Courier" size="4"> - in the script } which doesn't belong there or is missing something before it...), your line:

document.forms["entry"].selChoices.style.visibility = 'hidden ';

has a space inside the = 'hidden ' - solution: delete the space...
